No page edge
Pan and the surface keeps going. A project that grows for six months grows on one board instead of becoming board 1 of 4, which is where context normally goes missing.
Infinite whiteboard
A canvas with no edge, that opens the files you actually work with.
Most infinite whiteboards are infinite in the one dimension that costs nothing: space. Drop a 4K render, a rough cut, a 40-page brand manual or a character model on them and you get a placeholder rectangle and a download link. Ceyu opens all four on the canvas, at the size you need to judge them — and then lets the plan for that work sit on the same surface.
What "infinite" is worth, and what it is not
An endless surface only helps if you can put the real material on it and still find your way around. These are the parts that decide whether a board is usable at month three rather than on day one.
Video you can scrub
MP4 and WEBM play on the board and step frame by frame, so a note about a specific frame can be made on that frame instead of in a timestamped message somewhere else.
PDFs and 3D, not thumbnails
A multi-page PDF stays a document you can page through. GLB and GLTF models can be turned and looked at from the side the question is about.
Frames that give it structure
Frames group a region of the canvas and can be presented one after another, so the same board is both the messy working surface and the walkthrough you show a client.
On your own disk
Boards are stored locally first and stay editable with the network off. Cloud sync is opt-in and end-to-end encrypted, and an admin can switch it off for the whole workspace.
Import from where you are now
Boards come across from Miro, FigJam, Excalidraw and Mural, so trying this does not start with a blank canvas and a week of re-creating what you already had.
Where a different whiteboard is the better answer
If your team lives inside Figma, FigJam sits next to the design files and that adjacency beats anything here. If what you want is a big public template gallery or a third-party app marketplace, Miro's is far larger — ours is on the roadmap, not in the product. And if you need to drive the canvas from outside via an API, that is planned and not shipped, so this is not the tool for that job today.
Questions people ask first
What makes a whiteboard infinite?
There is no page edge and no fixed canvas size. You keep panning and the surface keeps going, so a board grows with the work instead of forcing you to start a second one. In Ceyu the practical limit is what your own machine can hold, not a document boundary someone chose for you.
Can I use an infinite whiteboard offline?
In Ceyu, yes. Boards are written to your own disk first, so a laptop with no connection opens and edits them normally. Cloud sync is a separate, opt-in layer; when it is off, nothing leaves the machine.
Which file formats can I put on the canvas?
JPG, PNG, WEBP, GIF and SVG for images, MP4 and WEBM for video, multi-page PDF, and GLB and GLTF for 3D models. YouTube, Vimeo, Loom and Sketchfab can be embedded as live objects.
Can I move an existing board over from Miro or FigJam?
Yes. Ceyu imports boards from Miro, FigJam, Excalidraw and Mural. Sticky notes, frames, shapes, connectors and images come across; anything that depends on a feature the source tool alone has does not.
Put one real board on it
Import a board you already have, or drop the heaviest file you own onto a blank one. That is the honest test, and the free plan runs it without a card.
